ASP: Find the length of a string using len and lenB function

my_string="Welcome to MySite.com"
Response.Write ( my_string )
Response.Write "Length of this string = " & len(my_string)
Response.Write "Number of bytes Required for this string = " & lenB(my_string)

The output of this will also show the number of bytes required. Here in this case it will print this:

Welcome to MySite.com
Length of this string = 21
Number of bytes Required for this string = 42
